Source

A text read as its source, what a rule found in it marked on it: each place tinted in its severity, a mark in the gutter on its line, the message and the rule under the pointer. Only ever on the source — a rendered preview shows none of it: one reads on one side and corrects on the other.

An annotated source

`source-view`: a text, its language, and annotations `{ line, column, end_line, end_column, severity, message, code }` — 1-based, the end exclusive, as filestate's verdicts give them. The editor of `code-input`, read only.

Source and findings side by side

`source-findings`: a finding clicked brings its place to the middle of the source, a place pointed at in the source lights its finding. One column under the other where the room is narrow.
